From the Earthworms (Perionyx excavates) gut the bacterial and fungal isolates were selected and identified using various biochemical tests. The bacterial isolates such as Bacillus sp, Escherichia coli, Micrococcus sp, Pseudomonas sp, Cellulomonas sp and the fungal isolates such as Aspergillus niger, Mucor sp, Penicillium sp and Rhizopus sp were identified. All the identified isolates were selected for characterization studies such cellulolytic, lignolytic and phosphate solubilization. Among the isolates Bacillus sp, Cellulomonas sp, and Aspergillus niger were found to degrade cellulose. In addition to cellulose degradation Aspergillus niger was found to degrade lignin and none of the bacteria responded to lignin. On the other hand Pseudomonas sp and Bacillus sp were found to solubilize tricalcium phosphate effectively. https://biomedpharmajournal.org/vol2no2/a-study-on-isolation-and-characterization-of-earthworm-gut-flora-of-perionyx-excavates/ Earthworms Perionyz excavates microbes
